PLACING THE SYSTEM IN SERVICE
1.
Confirm that system drains are shut and the system is free of
leaks.
2.
Open the remote system test valve (inspector’s test connection)
and any auxiliary drains to remove all air from the system.
3.
Close the alarm line ball valve to prevent alarms from operating
while the system is filling. Alarms and electrical panels (controlled by an
alarm flow switch on the riser) cannot be interrupted.
NOTE:
If alarm
activation is possible, notify local fire companies that the system is
being serviced.
4.
Open the water supply’s main control valve slowly.
5.
Allow the system to fill with water completely. Allow water to flow
from the remote system test valve (inspector’s test connection) and any
auxiliary drains until all trapped air is removed from the system.
6.
After a steady flow of water is established and all air is released
from the system, close the remote system test valve (inspector’s test
connection) and any auxiliary drains in the system.
7.
Record the system pressures. The system pressure gauge
should be equal to or greater than the water supply pressure gauge.
8.
Open the alarm line ball valve.
9.
Confirm that all valves are in their normal operating positions
(refer to table below).
10.
Notify the authority having jurisdiction, remote station alarm mon-
itors, and those in the affected area that the system is in service.
CAUTION
• The Series 751 Alarm Check Valve and supply piping must be pro-
tected from freezing temperatures and mechanical damage.
• For proper operation of alarms in a wet system, it is important to
remove all air from the system. Auxiliary drains may be required to
release all trapped air from the system.
Failure to follow these instructions could cause improper valve oper-
ation, resulting in personal injury and/or property damage.
CAUTION
• Take precautions when opening the water supply’s main control
valve because water will flow from all open system valves.
Failure to follow this instruction could result in property damage.
